Also, remember that there are some pretty iconic starting character builds like the single MM, the UC with gear to bump up encumbrance for those doing a NCB, and the whipster. Who could forget the whipster :)

At some point everyone HAS to try the GS, Haste, AS build but soon realize that the cost of equipping in unmaintainable.

Then there is the RBF build that reigned for so long until the EF builds started taking them apart. They are still pretty good, but not nearly so dominant.
